PAPER-REGISTERING MACHINE.

SPECIFICATION forming part of Letters Fatent No. 602,898, dated April 26, 1898. Application filed May 22, 1897. Serial No. 637,654. (No model.)

To ctZZ whom it may concern.-

Be it known that I, TALBOT O. DEXTER, of Pearl River, in the county'of Rockland, in the State of New York, have invented new and useful Improvements in Paper-Registering Machines, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

This invention relates more particularly to the class of paper-registering devices in which the registering instrument proper is equipped with a pin or point designed to enter a slit made in the paper for that purpose, said pin or point being made to engage the slit during a movement imparted to the sheet by suitable mechanism, and by said engagement the registering of the'sheet is effected.

The object of my present invention is to insure the engagement of the registering pin or point with the slit in the paper, so as to accurately register the sheet and then release the sheet from said engagement Without disturbing it from its registered position and without subjecting it to undue strain or lia bility of tearing or injuring the sheet.

To this end my invention consists, essentially, in the combination of suitable longitudinally-movable beds engagingthe sheet temporarily and during said operation traveling longitudinally and carrying the sheet with them, and registering instruments provided with pins or points for entering slits in the sheet during the movement imparted thereto by the beds; and the invention also consists in a novel construction and combination of mechanisms which cooperate to produce the aforesaid effects, all as hereinafter more fully described, and pointed out in the claims.

The invention is fully illustrated in the annexed drawings, in which Figure 1 is a side elevation of a paper-folding machine embodying my present invention. Fig. 2 is a plan View of the same. Fig. 3 is a vertical longitudinal section on line X X in Fig. 2. Fig. 4 is an enlarged vertical transverse section on line Y Y in Fig. 1. Fig. 5 is a side view of a modification of the mechana side view ofa modification of the means for causing the sheet-supporting beds to intermittentl y projectabove the plane of the sheetconveying tapes. Fig. 7 is a vertical transverse section on line Z Z in Fig. 6. Figs. 8 and 9 are side views of further modifications of the construction of the aforesaid beds and means for operating the same. Fig. 10 is a vertical transverse section in line U U in Fig. 8 of the drawings. Fig. 11 is an enlarged transverse section of the sheet-supporting bed. Fig. 12 is an enlarged side view of the registeringinstrument. Fig. 13 isaplan View of the same. Fig. 14 is an enlarged side View of the cam which actuates the registering instrument. Fig. 15 illustrates the action of the registering instrument, and Fig. 16 is an enlarged side elevation of my invention placed between the-sheet-arresting gage and foldingrollers of a paper-folding machine.

Similar letters and numerals of reference indicate corresponding parts.

A represents the main supporting-frame of the machine.

13 B designate the paper-folding rollers, and C the blade which introduces the paper between said rollers. a Ct are the tapes which convey the paper into the machine.

D is the rotary roller which by the aid of the usual drop-roller D feeds the paper to the tops of the aforesaid tapes.

or a" are the bars which are arranged between the tapes to assist in carrying the paper.

a a are the usual bars which support the portion of the paper lying beyond the folding-rollers, and E represents the gage which arrests the movement of the sheet carried into the machine by the tapes a ct.

All of said mechanisms, with the exception of certain features of the sheet-conveying tapes, as hereinafterdescribed, are arranged to operate in the usual and well-known manner and therefore require no detail description in the present case.

My present invention consists, essentially, of the beds F F, which are disposed at opposite sides of the longitudinal central line of the machine and either between the tapes a a or between the bars a C62, said beds being caused to intermittently project above the plane of the tapes to temporarily relieve the superimposed paper from the infl uence of the travel of the tapes and at the same time move inafter more fully explained.

the paper while the registering instruments operate upon the paper directly over said beds and thereby register the paper, as here- These mechanisms admit of awide range of modifications of their detail construction and of the means for actuating the same, as will be apparent from some modifications illustrated in the annexed drawings, and I therefore wish it to be understood that I do not limit myself specifically to the constructions which I now describe and which refer to the drawings hereto annexed.

For supporting the beds F F in their requisite positions to receive upon them the slitted portions of the paper I prefer to place beneath the tapes a a or bars a a, a transverse bar G, firmly secured at its ends to the frame A at opposite sides of the machine. On this bar are mounted the shoes H H, which are adapted to be shifted lengthwise of said bar or toward and from the longitudinal central line of the machine and are secured in their desired positions by means of set-screws b, inserted in screw-threaded eyes in a suitable portion of the shoe and engaging the aforesaid bar. The top of each of these shoes is provided with a longitudinal way or guide b, in which is mounted a slide H, to the top of which is suitably secured the bed F, which I preferably form of a fiat piece of soft indiarubber or other suitable material capable of obtaining sufficient frictional hold on the superimposed sheet to move the same with the travel of the bed for the purpose hereinafter explained. The purpose of these beds is to impart a secondary movement to the paper after it has been carried into the machine by said tapes and carry the paper in proper position to cause the registering instruments hereinafter described to engage the slits made in the paper for that purpose. These beds may be placed either between the feeding end of the machine and the folding-rollers B B, as shown in Figs. 1, 2, and 3 of the drawings, or between the folding-rollers and sheet-arresting gage, as shown in Fig. 16of the drawings, according to the location of the slits madein the paper. Suitable mechanisms are employed to impart longitudinal movement to said beds, as hereinafter described.

WVhen the beds F are mounted on the slides H, as before described, I connect said slides to a transverse barL, connected to the upper ends of rock-arms L, which are secured at the lower ends to a rock-shaft L actuated by an arm L attached to said shaft and held in contact with a cam N, secured to the shaft K. Said mechanism imparts intermittent reciproeating motion to the bed-supporting slides H.

The intermittent projection of the beds above the plane of the tapes may be edected either by raising and lowering the plane of said tapes or by raising and lowering thebeds. For raising and lowering the tapes as aforesaid I employ suitable vertically-movable frames, on which the shafts of the rollers which carry the sheet-conveying tapes a a are mounted. Said frames and the means for moving them as aforesaid may be constructed in various ways, two of which I have shown for exemplification in the annexed drawings.

Fig. 1 shows said frames to consist of horizontal beams J, provided at their ends with bearings for the shafts of rollers upon which the tapes a a run. The central portion of each of these beams is formed with a vertically-depending arm J ,which slides in vertical guides J 2 on the sides of the main frame A, To the side of said arm is pivoted a roller I, by which the frame J rides on a horizontally-sliding bar I the top of which is formed with a step 1 which causes the frame J to be lifted and lowered by a longitudinal movement of said bar. This movement is imparted to the sliding bar by means of either a suitable spring or a weight 27 forcing the bar in one directiomand the reverse movement is effected by means of a bell-crank b pivoted to a bracket on the main frame A and connected at one end to the sliding bar 1 and at the opposite end to a pitman'b which receives reciprocating motion from a camb attachedto a rotary shaft K, which extends across the machine and is j ournaled in suitable hearings in the frame A. The vertical movement of the frames J J is gaged to carry the tapes a a alternately to their requisite plane for conveying the paper into the machine, in which position the tapes are on a level with or slightly above the plane of the beds F F and to a plane beneath that of the said beds to cause the delivered sheet to rest on the beds and on the usual bars Ct at between the tapes. I do not, however, limit myself to the use of the before described mean-s for imparting the vertical movement to the frames J J, as said effect may be produced by othermechanisms, one species of which I have illustrated in Fig. 5 of the drawings and consists of vertical guides 1 l, secured to the main frame A at opposite sides of the machine and receiving through them the ends of the shafts 2 2 of the tape-rollers 3 and 4. To said ends of the shafts are connected the upper ends of toggle-levers 5 5, the lower ends of which are pivoted to the sides of the main frame A. The toggle-levers of each of the two sets at opposite sides of the machine are coupled together by a rod 6, connected to said levers at the junction of their arms to compel them to operate in unison. One of the toggle-levers of each set has connected to the junction of its arms a pitman 7, which receives reciprocating motion from a cam 8, attached to a rotary shaft 9, extending across the machine and mounted in suitable bearings thereon. All of said toggle-levers are deflected in the same direction by the weight of the shafts 2 2, supported thereon, and by said deflection the pitman is forced in opposite direction from the movement imparted to it by the aforesaid cam. However, the beds F F can be caused to intermittently project above the plane of the tapes a a without raising and of the drawings.

lowering said tapes as aforesaid by mounting the bed-supporting shoes H H on a verticallymovable cross-bar 19, fastened at its ends to vertically-depending bars 10, which slide in vertical guides 11, secured to the sides of the main frame A, as illustrated in Figs. 6 and 7 Any suitable mechanism may be employed for intermittently lifting the cross-bar 1 9 with the superimposed bed-supporting shoes H H. The mechanisms employed for said purpose represented in the drawings consist of a roller 12, pivoted to each of the vertical bars 10 and riding upon a horizontal bar 13, which slides longitudinally in a suitable guide'ou the main frame and is formed with a step 14 on its top. A bell-crank 15 is pivoted to the main frame and has one end connected to the bar 13 and the opposite end connected to a pitmamwhich is forced in one direction by a rotary cam 16 and in the opposite direction either by a suitable spring or by a weight 17, as shown.

When the tapes a a are to be maintained in a uniform plane, said tapes run from the socalled pipe-roller or large roller D to rollers adjacent to the foldingu'ollers B B in the usual manner; but in case the plane of said tapes is to be raised and lowered, as hereinbefore described, it becomes necessary to employ fingers or plates 6 e to bridge the space between said pipe-roller and adjacent vertically-movable tape-roller, as shown in Fig. l of the drawings.

Further modifications of my invention relate to the construction of the intermittent sheet-carrying beds and the means for operating the same, as illustrated in Figs. 8 and 9 of the drawings. In either of these cases the bed consists of an endless belt 18, preferably rubber-faced and running on rollers 19 19, one of which is connected by a crossbelt 20 to a pulley 21 on the main tape-roller shaft 22, and thus the belt 18 is caused to travel reverse from the tapes a. The intermittent projection of said belt above the plane of the tapes as may be efiected by using in connection with the tapes maintained in a uniform plane vertically-movable frames 23 on opposite sides of the machine and having the shafts of the rollers 19 19 pivoted to them. Various means may be employed for alternately raising and lowering the frames 23. An eXemplificat-ion of such means is shown in Fig. 8 of the drawings, and consists simply of rollers 24, pivoted to vertical limbs 25, depending rigidly from the frames and sliding in vertical guides 26 on the main frame A. By means of the rollers 24 the frames 23 ride on longitudinally-horizontal bars 28, formed with vertical offsets 29, which during the movement of the bars pass back and forth under the rollers 2a and thereby cause the frames 23 to' rise and fall. Pitmen 27, connecting the bars 28 with cams or eccentrics 30, impart the longitudinal movement to said bars.

Fig. 9 shows the belts 18, sustained in a uniin Fig. 1 of the drawings, as hereinafter described.

, The purpose of the described intermittent sheet-carrying beds is to partially relieve the sheet from the influence of the traveling sheet-conveying tapes and subject the sheet to contact with the friction-surfaces of said carrying-beds and thereby check the rapid motion of the paper near the end of its approach to the gage or stop E and subsequently move the sheet sufficiently to cause the registering instruments to perform their required functions. These instruments pertain to the type usually designated pointfeed, in which a point or pin attached to the instrument enters into a slit made in the paper for that purpose. Said engagement with the slit arrests the movement of the sheet carried by the aforesaid beds. 1 do not limit myself to any specific construction of said registering instruments, as the same maybe varied .in many respects without departing from the spirit of my present invention. I prefer, however, to construct and operate the registering instruments in the following manner: Across the machine, above the plane of the tapes (1, extends a rod d, mounted on suitable supports secured to the frame A. On this rod are mounted loosely the arms 0 o of the registering instruments. These arms extend in this case toward the feeding end of the machine, as shown in Figs. 1 and 3 of the drawings, and have their free ends directly over the beds F F and equipped with the registering pins or points 0, which are inclined toward the gage E or folding-rollersB. The lower ends of these pins or points are preferably, bent into a nearly or quite horizontal position to allow them to slide on the paper and guard against tearing the same.

' The aforesaid inclination of the registering pins or points facilitates their entrance into the slits in the sheet as well as their withdrawal from said slits in the operation of registering the sheet.

In cases when the beds F F are arranged to move vertically, as hereinbefore described, the arms 0 0 may be sustained stationary and in positions to allow the paper to be brought in contact with the registering-pins c by the rising of the beds F F, lifting the paper; but in machines having the said beds confined in a uniform plane the arms 0 c are to be arranged to oscillate, so as to carry the registering-pins to and from the aforesaid beds. For this purpose I prefer to connect the arms 0 c movably to the rod (Z and form them with heel extensions o with which engage intermittent oscillatorylevers f, attached to a rockshaft f. Said levers impart to the arms 0 c a corresponding oscillatory motion, which causes the registering-pins c to be carried alternately to and from the beds F F and bear on the paper at the proper time to allow said pins to enter the slits made in the paper for that purpose, and after thus registering said paper rise therefrom and allow the sheet to be drawn into the bite of the folding-rollers B B. Said lifting of the registering-pins has to be limited to a slight elevation, so as to merely relieve the paper from the pressure of the pins and allow the paper to be readily withdrawn therefrom, as aforesaid, without danger of injuring the paper or disturbing the sheet from its registered or alined position. However, a further subsequent lift is required of the registering-pins in order to allow the next succeeding sheet of paper to be carried freely under said pins by the tapes a a. The aforesaid action of the registering instrument is illustrated in Fig. 15 of the drawings. To impart this stepped upward movement to the registering-pins, I employ a cam h, formed with stepped faces h if, as shown in Fig. 14 of the drawings. This cam actuates the rock-shaft f by means of a rod 11, connected at one end to an arm i, fastened to the said rock-shaft and receiving intermittent and stepped reciprocating motion from said cam.

v In order to allow the described registering instruments to press their pins 0 with the desired degree upon the paper, I set the levers f in such positions on the rock-shat t f as to leave a slight play between said levers and heel extensions 0 of the registering-arms when said arms rest with the registering-pins upon the paper, and to the rod d I adjustably connect, adjacent to the said arms, collars j, to which I attach a coil-spring], terminating with extensions, which bear on the arms a suitable distance from the rod d, and thereby cause the registering-pins to press with the desired degree upon the paper. By turning the collars j on the rod 61 the tension of the springs can be adjusted.

The operation of my invention in a paper,- folding machine is as follows: The paper is fed into the machine by means of the droproller D and subjacent roller D, from whence the sheet is carried along by the tapes a a until said sheet comes in contact with the gage E, by which it is arrested in its movement and caused to lie with its central portion across the top of the folding-rollers B B in the usual manner. During this operation the tapes are carried in a higher plane than the beds F F, and the registering instruments are sustained in their extreme elevations to prevent said parts from interferingwith the aforesaid travel of the sheet. Said beds, however, are made to project above the plane of the tapes in time to partly check the movement of the sheet, so as to prevent its rebounding from the gage E. While the beds are in said position the registering instruments descend and press the registering-pins 0 onto the sheet directly over the beds, with which the paper is thus brought into more intimate contact. Said beds are then made to move longitudinally and by said movement draw the sheet with it and at the same time cause the registering-pins to enter into the slits made in the paper. As soon as said pins are thus entered they relieve the sheet from downward pressure and to a great extent from frictional contact with the beds. The registering-pins are therefore enabled to stop the movement of the sheet and retain the same in its registered position without danger of straining or tearing the sheet at the slitted portions thereof. As soon as this registering is effected the folding-blade O descends and tucks the sheet into the bite of the folding-rollers B B, and at the moment said blade strikes the sheet the registering instruments rise slightly to relieve the sheet from downward pressure and allow it to be drawn out of engagement with the registering-pins by the folding-rollers drawing the sheet down between them. The registering instruments then receive a second lift to raise the pins 0 farther from the path of the succeeding sheet of paper.

The slits in the paper herein referred to are made by cutters or points set in the bed of the printing-press for the aforesaid purpose, and in many cases the printer sets those outters in positions to make the slits at points which causes them to be located between the gage E and folding-rollers B B when said sheet is carried into the paper-folding machine. Hence it becomes necessary in such cases to place the registering instruments in corresponding positions in the folding-machine, as represented in Fig. 16 of the drawings, and when so arranged the registering instruments are to be placed reverse from the position shown in Figs 1 and 3 of the drawings, so as to cause the registering-pins c to be inclined from the gage E or toward the folding-rollers B B, and the subjacent beds F F are made to move longitudinally and in unison with a gage E, which in this instance is made to alternately advance to and recede from its sheet-arresting position in a manner similar to that shown in my Letters Patent No. 567,564, dated September 8, 1896, and as illustrated in Fig. 16 of the drawings hereto annexed, in which E represents the aforesaid movable gage, which rides on longitudinallymovable horizontal bars 70, each of which is supported at one end on a roller Z, j ournaled in brackets Z, mounted on the sides of the main frame A. The opposite end of the bar 70 is supported by an arm m, fastened in a suspended position to a rock-shaft m and connected at its lower end to a block is, formed on or otherwise fastened to the bar 70. A screw-rod n adjustably connects the gage E to the block 70. The rock-shaft m receives motion by means of a lever 12., fastened at one end thereto and having pivoted to its opposite end a roller 0, by which it bears on a rotary cam 0', which, in conjunction with a spring-actuated rod 0 imparts oscillatory motion to the lever n.

The beds F F are disposed between the sheet guiding and supporting bars a and se cured to slides n riding in shoes n mounted on a cross-bar G,which is secured at its ends to the sides of the main frame A. The slides 72 are connected to the reciprocating supporting-bar k of the intermittently-receding gage E by straps or links 72. and are thus caused to move synchronously with the gage E.

In connection with the beds F F, arranged in the paper-folding 1nachine,as last described, I place the registering instruments reverse from the positions shown in Figs. 1 and 3 of the drawings, so as to cause the registeringpins 0' to be inclined toward the folding-rollers B B and allow the sheet to be easily drawn out of engagement with said pins by the folding-rollers drawing the sheet down between them.

lrVhen myinvention is arranged as last described, the operation is as follows: The sheet having been carried into the folding-machine and arrested by the gage E, the tapes are made to drop from their operative plane, so as to allow the sheet to rest on the bars a and e and at the same time ride on the beds F F, which at that moment are stationary. The gage E then immediately recedes and causes the beds F F to move correspondingly and slightly advance the sheet, and in this movement of the sheet the registering-pins 0 enter into the slits in the paper and thereby register the sheet.
